public class IlvPolylineChartRenderer
extends IlvSimpleCompositeChartRenderer
implements IlvSuperimposedRenderer
```
A renderer displaying polylines. This renderer creates an instance of IlvSinglePolylineRenderer for every data set in the connected data source. An IlvPolylineRenderer supports two representation modes:
- Superimposed: polylines are drawn on top of each other. This mode corresponds to the SUPERIMPOSED constant.
- Stacked: polylines are stacked, so that each one displays the contribution of an y-value in a set of several y-values. This mode corresponds to the STACKED constant.
The following figure illustrates these representation modes:

  - SUPERIMPOSED
```
public static final int SUPERIMPOSED
```
    Mode type for superimposed polylines.
    
    See Also:
    
    setMode(int), Constant Field Values
  - STACKED
```
public static final int STACKED
```
    Mode type for stacked polylines.
    Two stacking modes are available:
    - Default mode: All the y-values for a given x-value are summed.
    - 100% mode: Each point represents the percentage it contributes to the sum of all the y-values for a given x-value.
    You can switch between the two modes with the setStacked100Percent(boolean) method.
    Note: This mode works best with data sets whose x-series are sorted in ascending order (see IlvDataSet.isXValuesSorted()). If stacking is performed according to same x values (see setStackedByIndex(boolean)), data sets that are not sorted this way will be implicitly sorted for display, like the class IlvXSortedDataSet does.

  - setStacked100Percent
```
public void setStacked100Percent(boolean stacked100)

    Specifies whether the stacking is scaled to 100. If stacked100 is set to true, the sum of all the y-values for a given x-value is scaled to 100. Each bar represents the percentage it contributes to this sum. This method is only meaningful when the mode of the renderer is set to STACKED.
    
    Parameters:
    
    stacked100 - The new stacking mode.

  - isStackedByIndex
```
public boolean isStackedByIndex()
```
    Indicates whether the stacking is based on data set indices rather than on X values. This method is meaningful only when the mode of the renderer is set to STACKED.

    See Also:
    
    setStackedByIndex(boolean), setMode(int)
  - setStackedByIndex
```
public void setStackedByIndex(boolean stackedByIndex)
```
    Specifies whether the stacking is based on data set indices rather than on X values. If stackedByIndex is set to true, the Y values are computed by accumulating the Y values with the same index, regardless of their X values, and the X values of the second, third, etc. data sets are ignored. If stackedByIndex is set to false, the Y values are computed by accumulating the Y values with the same X value, regardless of their index in the data set. This method is meaningful only when the mode of the renderer is set to STACKED.
